Description

Technical field

[0001] The invention relates to a telecommunications chip card for carrying personalization data, to a handset and to a method thereof.

Background and related art

[0002] In network technologies such as GSM and UMTS, a telecommunications chip card is used in mobile terminals, ensuring the integrity and security of the subscriber's identity data. In UMTS and GSM it may be called the UICC or UMTS Integrated Circuit Card.

[0003] Mobile TV is known as the technology that brings TV services to mobile devices. Depending on the receiver, it may combine the services of a mobile phone with television content. One way of delivering mobile TV is using a one-way dedicated broadcast network. These include digital video broadcasting-handheld (DVB-H), the digital video broadcast satellite service to handsets (DVB-SH), digital multimedia broadcasting (DMB), TDtv (based on TD-CDMA), 1 seg (based on ISDB-T), DAB and MediaFLO.

[0004] One of the drawbacks of using a unidirectional dedicated broadcast network, such as terrestrial transmissions, is the limitation of interactivity services with an easy implementation and with the possibility of deployment in a wide variety of mobile devices.

[0005] There is therefore a need for a telecommunications chip card or UICC for carrying personalization data, an improved handset and a method adapted for performing in accordance with the invention.

[0030] Fig. 1 shows a block diagram of a handset that includes a first handset entity 101, a chip card reader 102 for reading a chip card 103. The chip card further comprises a first applet manager 104, a first applet 105 and may include a second applet 106. The first applet 105 further comprises the first control data 107 and the second applet 106 may comprise a second control data 108.

[0031] On the handset startup, the first handset entity sends a registration to the first applet manager 104. The first applet manager 104 forwards this registration to the at least first applet 105. The first applet 105 sends to the first applet manager 104 the at least first control data 107. The first applet manager then forwards this first control data to the first handset entity 101. The first handset entity 101 receives a first data event 109 and compares the first data event 109 with the at least first control data 107. Based on this comparison, the first handset entity 101 sends at least a portion of the first data event 110 if the portion of the first data event 110 corresponds to at least one of the at least first control data 107. The first applet manager 104 forwards the portion of the first data event 110 to at least the first applet 105. At least the first applet 105 processes the portion of the first data event 110 for generating a first return signal to the first applet manager 104. The first return signal is then sent from at least the first applet to the first applet manager.

[0032] The second applet 106 may also be present in the chip card or may be added at a later point through an over the air update. This second applet 106 generates a second control data 108 and performs following the steps of the invention. The presence of the first applet manager 104 even by having a first applet 105 assures the possibility of updating the chip card by adding a second applet 106 or a plurality of applets. Alternatively, at least the first applet manager and at least the first applet may be implemented by a single applet. The applet manager and the applet may be implemented as independent card applets or java card applets, or communicating together on a single card applet or java card applet. The chip card may be also implemented as a secure element within a handset and perform all the operations according to the invention.

[0033] The registration of the first handset entity 101 may include a predefined URL on the first applet manager 104, using for example a command as get/register. A predefined URL is understood as a Uniform Resource Identifier (URI) or any syntax for global identifiers of network retrievable documents. The first applet manager then may pass the request or the registration to other applets as the first and second applet 105, 106 that will answer with a series of events or control data to register on the first applet manager or the first handset entity. This information may include adding the URL of the applets for the further direct access. When the handset is receiving digital data broadcasts from a mobile TV broadcasting network, the first handset entity may receive a portion of these digital data broadcasts and this portion may be called the first data event 109.

[0034] One of the advantages of the embodiments is that allows implementing new services and interaction with the first handset and with the first handset entity using only the chip card. All these types of services and small applications are stored in the applets that are managed by the first applet manager. Another advantage of the embodiments is that allows an interaction from the telecommunications chip card with the different elements of the network as the digital data broadcast network (or mobile TV network), with the rendering means (as a media player) and with the user that handles the handset. The digital data broadcast may be compliant with one of the the mobile TV broadcasting networks as DVB, ISDB, and DMB. The mobile telecommunications network may be compliant with the standards as GSM, UMTS, WiMax. The interaction of the handset and handset entities may be understood as a generic service framework running in the telecommunications chip card.

[0035] Fig. 2 shows a sequence of operation diagram. The sequence of operation diagram depicts the steps performed and the messages exchanged between the first handset entity, the first applet manager, and the first and second applet. First the first handset entity sends a registration to the first applet manager 201. Then, this registration is forwarded from the first applet manager to the first and second applet 202. The first and second applets generate a first and second control data that is sent to the first applet manager 203. Then, the first and second control data is forwarded from the first applet manager to the first handset entity 204. This first and second control data is used for comparison with the first data event 205. If the portion of the first data event corresponds to at least one of the first and second control data then the portion of the first data event is sent to the first applet manager 206. This portion is then forwarded to the first and second applets 207. The applets process the portion of the first data event 208 and generate a first return signal to the first applet manager 209.

[0036] Fig. 3 shows a block diagram of a handset including a first handset entity 101 and a chip card reader 102. Fig. 3 further shows a chip card 103. The elements in the embodiment shown in fig. 3 that corresponds to elements of the embodiment of fig. 1 have been designated by the same reference signals. The first handset entity 101 is a rendering means used for rendering the first data event. On the handset startup, the first handset entity calls a predefined URL on the first applet manager and requests a registration. The first applet manager 104 passes the request to all the applets 105, 106 that responds with the first and second control data 107, 108. This control data may include the URL for a direct access to the applets. The first data event is related to a digital data broadcast that may include video, video content or electronic service guide. This first data event has been previously processed by a second handset entity 301. When the first handset entity 101 is received in the first data event 109 it compares the first and second control data 107, 108 with the received first data event 109. If the first data event corresponds to at least one of the first and second control data 107, 108, then a portion of the first data event is sent 110. The first and second control data 107, 108 may be seen as information related to the first data event as changes in the first handset entity as turned off or on or changing the stream of the digital data broadcast or the channel of the network. The portions of the first data event 110 may include the time and the type of stream or some notification about the channels that are rendered using the first handset entity.

[0037] When the first data event matches at least one of the first and second control data and the portion of the first data event 110 is sent to the first applet manager, the first applet manager 104 forwards this information to the applet whose corresponding the matching of the control data. For example, if the first applet sends a first control data 107 to the first handset entity with the information of e.g. a user zapping a channel, then the portion of the first data event 110 will be sent to the specific first applet 105 for further processing. The first applet 105 then generates a first return signal 111 to the first applet manager 104. The first applet manager 104 then forwards the first return signal 111 to the first handset entity 101.

[0038] This first return signal 111 may include for example notification of adult/violent programs, or notifications of a price change, as well as advertisement to be rendered by the first handset entity. One of the advantages of the embodiments is the type of services that may run on one of the applets. One of the services is related to the parental control, where a dedicated applet implements a set of rights introduced by a user in collaboration with the rendering means or the media player. The applet transmits a description of a rich interactive application. This description may be for example in the form of a HTML page that is displayed as pop-up windows with the restrictions to be applied to the user of the rendering means.

[0039] Fig. 4 shows a block diagram of a handset including a first and second handset entity and a chip card reader, and a chip card comprising a first and second applet manager.

[0040] The first handset entity is a rendering means and the second handset entity is a demultiplexer. The elements in the embodiment shown in fig. 4 that correspond to elements of the embodiment of fig. 1 have been designated by the same reference signals. After the comparison between the first data event 109 and the first and second control data 107, 108 done by the first handset entity 101 has been completed, the series of signals between the first handset entity and the first applet manager 104 are changed as the portion of the first data event 110 and a first return signal 111. Depending on the content of the first return signal 111 that arrives at the first handset entity 101, a first response 402 may be generated. This first response 402 is forwarded to the first applet manager 104 that may require consent the first response 402 to the second applet manager 401. The second applet manager 401 then uses this first response 402 for handset or chip card customization and administration purposes. This handset or chip card customization and administration might include, for example, modification of the handset parameters as the user interface, the applications, user data, and the possibility of making available new services to the handset. The embodiment is particularly advantageous as it may enable new services to the users of the handset by using the great bandwidth of the digital data broadcast network if the for example cellular mobile network as UMTS or GSM is not available. The first return signal 111 that was sent to the first handset entity 101 may include information regarding a request to the user of the handset about the parameters to be used during the handset customization.

[0041] In a further advantage of the embodiments, the chip card is able to store and manage data content related to the electronic service guide, using the digital data broadcast or the cellular mobile telecommunications network to upload information or web pages describing programs displayed on the electronic service guide and rendered by the rendering means. Subsequently, the user of the rendering means has access to this information using the applets that interact with the rendering means.

[0042] Fig. 5 shows a block diagram of a chip card 103, a handset that comprises a first and second entity 101, 301 and a chip card reader 102 for reading the chip card 103. The chip card further comprises a first and second applet manager 104, 401. The second applet manager 401 is being adapted for communicating with a cellular mobile network 501. When the first handset entity 101 that corresponds to rendering means starts receiving a first data event 109 that is related to the digital data broadcast, it compares the received first data event 109 with the first and second control data 107, 108. Based on the comparison made by the first handset entity 101 a portion of the first data event 110 may be sent to one of the first and second applets 105, 106 and a first return signal may be generated by one of the applets and sent to the first handset entity 101. If the first return signal 111 requires a response from the first handset entity, then the first response 402 will be generated and sent to the first applet manager. Then, the first response 402 is forwarded to the second applet manager 401 that allows connecting to cellular mobile network 501 and sending this first response 402 to the network 501.

[0043] One of the advantages of the embodiments is that allows the user of the handset entity to use a feedback channel in order to respond to a request sent by the digital data broadcast network. As the digital data broadcast network is in general a unidirectional network, and then the second applet manager 401 manages all the data so that it can be fed back to the system. Another advantage of the embodiments is the possibility to manage a voting or advertisement request from the chip card. This voting request might be generated by a mobile network operator using one of the digital data broadcast networks to send or trigger a vote during watching one of the channels in the rendering means. This information will be first processed by the applet manager connected to the multiplexer that will further send a request to the applets. Subsequently, the data will be transferred to a second applet manager there is coupled to the rendering means, sending all required information to the rendering means for setting a rich interactive application, for example in the form of an HTML page on the main screen of the media player and asking the user to generate a vote. The response of the rendering means will be forwarded to the applet manager that is adapted for processing and sending the data to a mobile cellular telecommunications network. Alternatively, the applet may be adapted for processing and sending the data to the mobile telecommunications network.

[0044] A further advantage of the embodiments is that allows collecting statistic information regarding the use of the rendering means and the channels displayed by the rendering means and watched by the user. The applets in the chip card will track the user habits by monitoring parameters as the channel, the time, duration and frequency of use and downloading this information on a regular basis using the feedback channel provided by a cellular telecommunications network. The mobile network operator then will be able to analyze and use this data to define and improve the usage of its services.

[0045] Fig. 6 shows a block diagram of a handset comprising a first and a second handset entity and a chip card, wherein the chip card reader is adapted for reading a chip card. The elements in the embodiment shown in fig. 6 that correspond to elements of the embodiment of fig. 1 have been designated by the same reference signals. In this first embodiment the first handset entity is the multiplexer and the second handset entity is a rendering means. On handset startup, the multiplexer calls a predefined URL on the first applet manager. The first applet manager 104 forwards this request to all applets first and second applet 105 and 106, that responds with a first and second control data 107, 108 to be registered in the first applet manager 104 and alternatively in the first handset entity 101.

[0046] When the handset receives a first data event 109 from a unidirectional broadcast network 601, the first handset entity 101 starts comparing this first data event 109 with at least the first and second control data 107, 108. If a portion of the first data event corresponds to at least one of the first and second control data 107, 108, then the portion of the first data event 110 will be sent to the first applet manager 104. The first applet manager 104 then forwards the portion of the first data event 110 to the applet that has sent the matched control data. At least one of the first and second applets 105, 106 processes the received portion of the first data event 110 and sends a first return signal 111 to the first applet manager 104. The first return signal 111 can be used by the first applet manager 104 for handset customization or handset administration purposes. Alternatively the first applet manager 104 if required by the service that is provided will forward the first return signal 111 to a second applet manager 401 that communicates with the second handset entity 301.

[0047] The first return signal 111 that is received by the second handset entity may be for example a request for a voting service to the user of the handset and the second handset entity, or an advertisement to be displayed by the second handset entity. This content of the first return signal 111 could be also a user interface parameter or applications being used by the second handset entity that will be updated or upgraded by the first return signal. The second handset entity 601 is at the same time rendering the second data event 602 that is provided by the first handset entity 101. The second data event 602 corresponds to the rendering portion of the first data event 109 that has been separated by the first handset entity 101.

[0048] Another advantage of the embodiments is that the mobile network operators are able to use the high speed channel of the mobile TV broadcasting network (or digital data broadcast network) to transport non-mobile TV data to be used by the telecommunications chip card and by the handset to perform different actions such as device management, dynamic management of mobile services and handset customizations.

[0049] The invention executes two new types of card application or applets to enable the interactivity between the user of the handset and the mobile network operator. A first type of card applications interact with generic data transmitted over the digital data broadcast or the so called mobile TV broadcasting network. The second type of card interacts directly with the mobile TV, or so called rendering means. These two applet managers can alternatively communicate to share the type of application and re-transmit it to the rendering means or as a feedback channel using the mobile cellular telecommunications network. The first type of card application receives data through the multiplexer coming from the digital data broadcast network and the second type of card application interact with the rendering means or the media player to display services, get user entries and if necessary transfer request to the mobile network operator or mobile telecommunications network. This type of service framework relies on the smartcard web server applications (SCWS) or any kind of SIM Toolkit mechanism as defined in the telecommunications standards such as ETSI and 3GPP.

[0050] In further embodiments the first and second control data 107, 108 may be updated using the unidirectional broadcast network 601 that sends the data and that is received by the first handset entity that further forwards the information up to the applets that modifies the content of the first and second control data 107, 108. The second applet manager 401 may be connected to a third and a fourth applet 603, 604 that contained a third and fourth control data 605, 606 respectively. This third and fourth control data 605, 606 may be also updated or modified through the unidirectional broadcast network 601. The third and fourth applets 603, 604 are used in general to send and receive control data to and from the second handset entity 301, whereas the first and second applet communicate in general with the first handset entity 101 using the first applet manager 104. All responses or feedbacks may be sent using the cellular mobile network as a feedback channel and using one of the first and second applet managers.

[0051] Fig. 7 shows the use of a telecommunications chip card for buffering of a first data event from a rendering means. Alternatively, the buffering of a first data may be sent from a demultiplexer. The telecommunications chip card may buffer the data event in a storage medium.

[0052] A further advantage of the embodiments is that allows time shifting from the telecommunications chip card. Time shifting allows depending on the capacity of the telecommunications chip card to store the recorded programs while the user is not available or to manage the VCR service that is storing the recording programs on the server. Telecommunications chip card with a large storage medium will be able to store the stream content that is generally sent to the media player on the chip card instead of using the internal memory of the handset. When the user makes a request, the stored stream in telecommunications chip card will be forwarded to the rendering means or to the media player to play the recorded sequence. This service has the advantage that it may use the telecommunications chip card as a storage medium when the internal handset memory is not available or it is full. In telecommunications chip card with little amount of storage, the chip card sends a VCR request to a time shifting server. This server will record the digital data broadcast while the user is requesting to do so. When the user makes a request to play the recorded stream, the time shifting server sends the stream using a unicast medium. The chip card and the applets will then manage the communication between the time shifting server and the rendering means.
